In order to build an arm64 kernel with clang <6.0, we need to work around LLVM bug 30792 by using -mno-implicit-float instead of -mgeneral-regs-only.
This patch set adds macros for checking clang version, and enable the workaround only for affected compiler versions.
Greg Hackmann (1): arm64: use -mno-implicit-float instead of -mgeneral-regs-only
Sami Tolvanen (2): kbuild: add clang-version.sh kbuild: add cc-if-name-version and compiler-specific variants
